Description
図1は、実施の形態1に係る車載制御装置が適用された車両の概略構成を示す図である。図1を参照して、車両200は、DC充電ユニット10と、DCインレット13と、車両ECU50と、DC/DCコンバータ60と、駆動バッテリ71と、補機バッテリ72と、走行駆動部80と、駆動輪90と、入力装置210と、報知装置220と、電装品230と、アクセサリソケット240とを備える。走行駆動部80は、PCU81とMG(Motor Generator)82とを含み、駆動バッテリ71に蓄えられた電力を用いて車両200を走行させるように構成される。DC充電ユニット10及び走行駆動部80は、車両ECU50によって制御される。この実施の形態に係る車両ECU50、DCインレット13、電装品230は、それぞれ本開示に係る「車載制御装置」、「直流電力用充電口」、「所定の補機類」の一例を構成する。
非対応設備では、電源400が電圧200Vの3相交流電源である。非対応設備の本体310は、図1に示される構成に加えて、AC/DCコンバータ及び昇圧回路を含む電力変換回路(図示せず)をさらに備える。電力変換回路は、電源400から供給される交流電力に所定の電力変換を行ない、約50kW(定格電圧400V、定格電流125A)の直流電力を充電ケーブル320へ出力する。こうした給電設備は、いわゆる急速充電器に属し、急速充電を目的とする。このため、非対応設備を用いた急速充電中にDCマイルームモードを実行して補機類を駆動すると、他の車両のユーザの利便性を阻害するおそれがある。
本開示の実施の形態2に係る充電システムについて説明する。実施の形態2は実施の形態1と共通する部分が多いため、主に相違点について説明し、共通する部分についての説明は割愛する。
設備情報は、給電設備がDCマイルームモードに対応しているか否かを示す範囲で任意である。たとえば、給電設備が公共/非公共のいずれの設備であるかを示す情報を、設備情報として採用してもよい。そして、充電システムが、以下に説明する給電設備(すなわち、DCマイルームモードに対応している第4対応設備)を含んでもよい。
